Comparing quotes

Four things to check on any new boiler quote

Surveyed, or guessed?
Ask whether a heat-loss calculation is done. An oversized boiler wastes money every year.
What is excluded?
Ask what is not included, such as filters, flushing, controls or flue changes, and get it in writing.
Warranty length and conditions
Manufacturer warranties often depend on installer accreditation. Ours run up to 12 years depending on the model.
Is the installer Gas Safe?
Check the Gas Safe ID on the register. Ours is 599015.
Repair or replace?

Is it worth repairing your old boiler instead?

If your boiler keeps breaking down, compare the cost of repairs with replacement. Our guide to boiler repair vs replacement explains how to decide, and our guide to common boiler problems covers faults you can check yourself.
